Looking for a couple electric (12VDC) pumps that are made for oil. Basically I want to make a miniature (10 gallons or so) transfer tank for hydraulic oil for work to put in the bed of my work truck. Space is limited and so I'm looking for a submersible electric pump that can flow hydraulic/motor oils at a few gallons (4-6 ish) per minute.

Anyone know of any such thing?

I don't really have the space for a mechanical hand-pump on top of the tank but if that's all there is then I guess that's what would have to happen.

Google brings up a couple options, but I'm wondering if anyone has any firsthand experience.

Try an old in tank gasoline pump? Some old ranger and f-150 trucks used a two pump system where the in-tank was a low pressure feeding an inline high pressure for early efi systems - 86 to 88 I believe. I guess it would depend on viscosity but may be worth a try. Might be able to re-purpose the tank too.

What about one of the Shurflow diaphragm pumps? People have used them for oil pumps on rear mount turbo setups. Normaly they dont last a long time b/c of heat, but if at ambient temps Id think they would last.
